hobby stores sell engravers for less than 20$ theyre great for marking personal property in case its stolen so it can be recovered and alot of other stuff, they can mark anything plastic, wood or metal

Here is a pic of a tag I had last year from the MHDGC bag tag. I love these and they are worth the extra money we pay in dues, (it's 20$ to join our club, that year we got a sticker and a towel as well as the tag, this year we got a new designed tag and a really nice 32oz water bottle). And we have a massive last of the year tag match on Dec31 and keep which ever tag we get, then on teh 1st of January have new designed ones and a first tag match of the year.
The others in the picutre are Trophy tags. When Mile High Disc Golf Club does a tournament they give out Trophy Tags.

The gold one is a BADCO (aka Denver Disc Golf) Tag. IT's really heavy gold plated Copper medalion. Blue painted ones are the Ams, and the PRos have theirs Painted in RED.
